2 - SKILLS CHOICE:
Elemental Boon has a short duration and long cooldown, so it was dropped. But I won't denie that the bonuses it has are great.

I've read some reports saying that Astral Ally isn't worth, so it was dropped. Also, with the recommended pet spells you'll have a small army for yourself and Ice Prison + Hailstorm + Frozen Fate does a great crowd control.

Thunder Locus and Frost Wave are really good AoE, but in this build I choosed Hailstorm. To be honest, you even won't use Hailstorm for AoE, you'll just cast Hailstorm for the crowd control it causes stuning and freezing, and for the eletrical damage bonus the hailstorm tier has. After casting Hailstorm once, you'll spawn Prismatic Bolt to wipe your foes.

There weren't points left for Prismatic Rift, but if you play it correctly you won't need it.

Although many people says that at end game you won't have problems with mana, Charge Mastery is great for the 25% damage bonus that embermages receive when charged, and also gives a great help with mana issues at early game.

Elemental Attunement is necessary because at end game you'll spent a lot of time moving between your attacks with Prismatic Bolts, and keeping the status effects up are essential to deal a high damage with the brands (Fire Brand/Ice Brand/Lightining Brand).

Ice Prison is a great crowd control, so it was maxed.

To spend at least 1 skill point in Frozen Fate is mandatory for crowd control. But if you disagree, you may spend this point in Astral Ally.

Immolation Aura is a good defensive bonus.

Frost Phase is essential for mobility and dodging. One level is mandatory and enough.

Death's Bounty is a great help for survivability.

3 - LEVELING:
As soon as possible, take the skill point form magma spear and put it at Prismatic Bolt. Keep Prismatic Bolt at level 1 until your character is at least level 20 or more, or you'll have mana issues and the first levels of prismatic bolt doesn't greatly increase it's damage.

The second skill you'll need it's charge mastery. Get it to level 5 ASAP.

At the beggining the brands are not very effective without elemental attunement, keep that in mind when chosing what passive skill to upgrade. Get at least one level of each brand, them get level 5 of elemental attunement, then upgrade the brands.

Always keep a preference to get level 1 of the active skills, and then maximising the brands (ice/fire/lightiningh brands). When you start to invest skill points at any active skill, give a preference for it until it gets at a level multiple of 5, then start to invest at another skill. At the early game you'll really want the Hailstorm and Immolation tier 5 bonus.

Investing heavily in Ice Prison until it's maxed is not a bad idea. The crowd control it offers is essential for surviving.

4 - ROTATION:
1 - Always keep Elemental Protection and Immolation Aura up.
2 - If you're facing a boss or a elite, cast Elemental Overload and Dervish whenever you get charged and the cooldown is up. Also, use a vampiric spider egg or a warsnouts at the beggining of the battle.
3 - Use ice prison for crowd control. It's also very useful against bosses and elites, not only crowds.
4 - If you're facing a crowd or have health/mana issues, use Death's Bounty.
5 - Cast Hailstorm for the bonus it gives for eletrical damage with it's tier and for crowd control.
6 - Spam Prismatic Bolts.

At any moment during the rotation, run or use Frost Phase to keep distance from your enemies and dodging spells so you don't get killed. To stay still during a battle it's to flirt with death.

5 - HOTKEYS:
I like to put the Spells (Dervish/Elemental Overload/Elemental Protection), pet food and Immolation at the bar, so I can easily cast them (it also helps remembering to cast them). At the right click I rotate betwen skills using the hotkeys F1 (Ice Prison), F2 (Death's Bounty), F3 (Hailstorm), F4 (Prismatic Bolt) and F5 (Frost Phase).

6 - STATS:
Aim for the following stats, without bonuses:

STRENGHT 5
Strenght is useless for embermages.

DEXTERITY 53
Dex 53 gives critical and dodge chances ate base 10%.

FOCUS 342
The main stat for embermages, it increases the magical damage of skills.

11 - TIP:
Keep any VENDOR BOON SCROLL to use it only when you have a lot of money (at least 2 milion gold) and at an area level 100 or more (like Tarroch's Tomb at new game +). Then you may have the chance to buy one best-in-slot item.

12 - BEST-IN-SLOT ITENS:
There are many good wands and shields, use the ones you found with the best status according to the topic "Item Build".

Although the ascedant seems to be the best choice for gloves, belt and shoulder due to it's extra socket slot and higher armor, you should remember that you can add a second socket to the transcedent items. Despiste the fact that the trancendent physical armor is lower, the other item stats are much better.

And ascendant and trancendent items are from the same set, so with my recommendation you`ll have all the set bonuses till 8 pieces.

About the rings, you won't need to complete the Transcedent Set, because the alchemist ring of ember is so far superior to the trancendent ring that the last two bonus of the trancendent set are surpassed.

13 - BEST SOCKETS:
Weapon sockets: 1 rambren skull. If you have more than one socket slot, use rambren skulls and whorlbarb skulls at the ratio 1:1 with preference to rambren.

Armor/Trincket sockets: use at the ratio 2:1:1 Wfuntir Skull/Skull of Limoany/Skull of Riechliu. With all best-in-slot itens and adding an extra socket to the trancedent items and rings, you'll have a total of 20 armor sockets. At this point you should be using 10 wfuntir, 5 limoany and 5 riechliu.
